Primes¶
- Access Friction
- Proof-of- work selects on access to cheap energy and hardware, which is why proof-of-stake was designed as an alternative friction type — selecting on capital held rather than energy burned — to change who is excluded while preserving the entry-asymmetric Sybil resistance.
This sourceIntroduces proof-of-stake as an alternative entry-friction type that selects on capital held rather than energy burned while preserving the entry-asymmetric Sybil resistance, changing who is excluded.

PPCoin introduces proof-of-stake based on coin age as a replacement for proof-of-work's energy dependence, but gives energy efficiency, not exclusion or Sybil resistance, as the motive.
“Security level of the network is not dependent on energy consumption in the long term”

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
